In the figure shown below, m < 40 and ab =8. which equation could be used to find x?

B

Step-by-step explanation:

Since the triangle is right use the tangent ratio to solve for x

∠A = 180° - (90 + 40)° = 180° - 130° = 50°

tan50° = =

multiply both sides by 8

x = 8tan50° → B

if you mean

then it's c. 8, -7/3

but if you mean

then it is
